Frequent iCloud notifications, but I don't use iCloud
With some frequency, my Macbook Air will give me the notification, "This Mac can't connect to iCloud because of a problem." Each time I click "Later" to make the notification go away, but of course it keeps coming back. If I instead allow the prompt to take me to iCloud preferences, it asks me to log in to iCloud.
I'm not logged into iCloud on purpose. I've never used it, and I have no interest in ever using it in the future. How do I stop this notification from recurring?
